If you are using a computer with a functioning Ethernet port, you can use the Quick Installation Guide to quickly establish your ADSL connection and access the Internet. Guide Overview Introduction – Describes the Router and its key features. Provides an introduction to ADSL. Lists standards to which the Router complies. Contains a packing list. Hardware Installation – Discusses how to connect the Router to an Ethernet LAN. First Time Set Up – Provides information on how to configure the Router and establish the ADSL connection using the web-based manager. Web-based Configuration – Describes how to use the web-based manager to change Router settings and configure additional virtual connections (PVCs). Appendix A - Technical Specifications – Lists the technical specifications of the Router, including standards compliance. Appendix B - Low Pass Filters – Contains illustrated examples of how to use low pass filters. Before You Start Please read and make sure you understand all the prerequisites for proper installation of your new Router. Have all the necessary information and equipment on hand before beginning the installation. Installation Overview The procedure to install the Router can be described in general terms in the following steps: 1. Gather information and equipment needed to install the device. Before you begin the actual installation make sure you have all the necessary information and equipment. 2. Install the hardware, that is, connect the cables (Ethernet and telephone) to the device and connect the power adapter. 3. Check the IP settings on your computer and change them if necessary so the computer can access the web-based software built into the Router. 4. Use the web-based management software to configure the device to suit the requirements of your ADSL account. Requirements To install and use the Router you need a computer equipped with an Ethernet port (such as an Ethernet NIC) and a web browser. You may also need to use information given to you by your ISP or ADSL service provider. This information is stored in the Router’s memory and used to establish the ADSL connection and confirm your identity. Read the next page for more details about these requirements. Low Pass Filters Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering mechanism may be necessary to avoid mutual interference. A low pass filter device can be installed for each telephone that shares the line with the ADSL line. These filters are easy to install passive devices that connect to the ADSL device and/or telephone using standard telephone cable. Ask your service provider for more information about the use of low pass filters with your installation. Appendix B provides illustrated examples of how to install two common styles of low pass filters. vii DSL-500G ADSL Ethernet Router User’s Guide Operating System The DSL-500G uses an HTML-based web interface for setup and management. The web configuration manager may be accessed using any operating system capable of running web browser software. Web Browser Any common web browser can be used to configure the Router using the web configuration management software. The program is designed to work best with more recently released browsers such as Microsoft Internet Explorer® version 5.0, Netscape Navigator® version 4.7, or later versions. The web browser must have JavaScript enabled. JavaScript is enabled by default on many browsers. Make sure JavaScript has not been disabled by other software (such as virus protection or web user security packages) that may be running on your computer. Ethernet Port (NIC Adapter) Any computer that uses the Router must be able to connect to it through the Ethernet port on the Router. This connection is an Ethernet connection and therefore requires that your computer be equipped with an Ethernet port as well. Most notebook computers are now sold with an Ethernet port already installed. Likewise, most fully assembled desktop computers come with an Ethernet NIC adapter as standard equipment. If your computer does not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you must install an adapter, follow the installation instructions that come with the Ethernet NIC adapter. Router vs. Bridge Mode The DSL-500G can be used in two different mode or roles, a router mode or bridge mode. In bridge mode the device is intended to connect a single computer to the Internet or WAN (Wide Area Network) interface. In bridge mode the device is said to be invisible since it does not have an IP address. The IP address is actually configure on the computer connected to the Ethernet LAN interface. If you are using the device in bridge mode it is recommended that you run firewall software on the computer connected to it. Additional Software It may be necessary to install software on your computer that enables the computer to access the Internet (through computers operated by your ISP or service provider). Additional software must be installed if you are using what is called a “bridged” connection. For a bridged connection, the information needed to make and maintain the Internet connection is stored on your computer, not in the Router. This type of connection is similar to the arrangement used for analog dial-up Routers, but the connection speed is much faster. Various terms are to describe a bridged ADSL connection including the term “RFC 1483 Bridge” which is used in this guide. If your ADSL service is delivered through a PPP (Point to Point Protocol) or IPoA connection, the information needed to establish and maintain the Internet connection is stored in the Router. In this case, it is not necessary to install software on your computer. Account Information (User Name and Password) Most users will need to supply a user name and password used to access the service provider’s network (and ultimately, the Internet). This information is stored either in the Router’s memory or on your computer depending on the type of ADSL connection you have. ACCOUNT INFORMATION (PPP Connections Only) User Name: Password: Additional PVC Settings If you are using multiple virtual connections it will be necessary to provide additional VPI and VCI values for the device. These numbers define a unique route used on the ATM backbone of the WAN. Chapter 5 contains instruction on how to set up additional PVCs for accounts using more than one virtual connection. viii DSL-500G ADSL Ethernet Router User’s Guide Packing List Open the shipping carton and carefully remove all items.

One Quick Installation Guide hardcopy ix DSL-500G ADSL Router User’s Guide 1 Introduction This section provides a brief description of the Router, its associated technologies and a list of Router features. What is ADSL? Asymmetric Digital Subscriber Line (ADSL) is broadband access technology that provides high-speed digital data transmission and interactive multimedia applications for business and residential customers over ordinary telephone line. ADSL greatly increases the signal carrying capacity of copper telephone lines without interfering with regular telephone services. For the ADSL user, this means faster downloads and more reliable connectivity. ADSL devices enable high-speed Internet access without any loss of quality or disruption of telephone services. ADSL provides a dedicated service over a single telephone line operating at speeds of up to 8 Mbps downstream and up to 640 Kbps upstream. A secure point-to-point connection is established between the user and the central office of the service provider. D-Link ADSL devices incorporate the recommendations of the ADSL Forum regarding framing, data format, and upper layer protocols. Router Description and Operation The DSL-500G ADSL Router is designed to provide a simple, cost-effective and secure ADSL Internet connection for your small to medium-sized private network. The ADSL connection technology enables many interactive multi-media applications such as video conferencing and collaborative computing. The Router is easy to install and use. The DSL-500G connects to an Ethernet LAN or single computer via a standard Ethernet interface. The ADSL connection is made using ordinary twisted-pair telephone line with standard RJ-11 connectors. Router Features The DSL-500G ADSL Ethernet Router utilizes the latest ADSL enhancements to provide a reliable Internet portal suitable for most small to medium sized offices. DSL-500G advantages include: • Data rates up to 8 Mbps for downstream and 640 Kbps for upstream • Friendly web-based graphical user interface for configuration and management • Supports up to eight simultaneous virtual connections for a single ADSL account • Supports T1.413 issue 2, G.dmt and G.lite standards • Auto-handshake and rate adaptation for different ADSL flavors • Widest range of DSLAM interoperability • Supports bridged Ethernet over ATM (RFC 2684) • Built-in MIBs for SNMP management • Upgradeable firmware through TFTP 1 DSL-500G ADSL Router User’s Guide Front Panel Place the Router in a location where the LED indicators can be easily viewed. Figure 1. Front Panel Display with LED Indicators The LED Indicators read as follows: Power Steady green light indicates the unit is powered on. Status Blinking green indicates normal operation. ADSL: Link/Act Steady green light indicates a valid ADSL connection. This will light after the ADSL negotiation process has been settled. Blinking green light indicates an active WAN session. Ethernet: Link/ Act Steady green light indicates a valid Ethernet connection. Blinking green indicates an active Ethernet session. Rear Panel All cable connections to the Router are made at the rear panel. The factory-reset button is located here as well. Ethernet port, connect Ethernet cable here Factory Reset button ADSL port, connect ADSL cable here Power cord connects here Figure 2. Rear Panel Cable and Power Connections 2 DSL-500G ADSL Router User’s Guide 2 Hardware Installation In this chapter you will learn about the various connections you will need to make in order to use the Router. When selecting the location for the Router, allow ample room to access the connections on the rear panel. For convenience, try to place the Router near your computer so you can monitor the LED indicators. Allow some space above the Router for ventilation to avoid problems with overheating. Connect ADSL Line Use the twisted-pair ADSL cable (standard telephone cable) included with the Router to connect it to your telephone line. Simply plug one end of the cable into the ADSL port (RJ-11 receptacle) on the rear panel of the Router and insert the other end into the wall jack. Computer to Router Connection You can connect the Router directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed on a PC using the Ethernet cable provided as shown in this diagram. Figure 3. PC to Router Connection Connect Ethernet LAN to Router The Router may be connected to any 10/100BASE-TX Ethernet LAN. Any connection to an Ethernet concentrating device such as a switch or hub must operate at a speed of 10/100 Mbps only. When connecting the Router to any Ethernet device that is capable of operating at speeds higher than 10Mbps, be sure that the device has auto-negotiation (NWay) enabled for the connecting port. Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a crossed port (MDI-X). Follow standard Ethernet guidelines when deciding what type of cable to use to make this connection. When connecting the Router directly to a PC or server use a normal straight-through cable. You should use a crossed cable when connecting the Router to a normal (MDI-X) port on a switch or hub. Use a normal straight-through cable when connecting it to an uplink (MDI-II) port on a hub or switch. The Ethernet Link LED indicator will indicate a valid connection. The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that the cable connecting the LAN to the Router does not exceed 100 meters. 3 DSL-500G ADSL Router User’s Guide Hub or Switch to Router Connection Connect the Router to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through cable as shown in the diagram below: If you wish to reserve the uplink port on the switch or hub for another device, connect to any on the other MDI-X ports (1x, 2x, etc.) with a cross-wired cable or use crossover adapter. Figure 4. Switch to Router Connection Power On Router To power on the device: 1. Insert the AC Power Adapter cord into the power receptacle located on the back of the Router and plug the adapter into a nearby power source. 2. You should see the Power LED indicator light up and remain lit. 4 DSL-500G ADSL Router User’s Guide 3 Configuring the Router for the First Time The first time you setup the Router it is recommended that you configure the WAN connection using a single computer making sure that both the computer and the Router are not connected to the LAN. Once the WAN connection is functioning properly you may continue change settings to suit your network. This chapter is only concerned with settings up the WAN connection. The following chapter, Web-based Management Guide, describes the various menus used to configure and monitor the Router including how to change IP settings and DHCP server setup. Wan Configuration Summary 1. Connect to the Router To configure the WAN connection used by the Router it is first necessary to communicate with the Router through its management interface, which is HTML-based and can be accessed using a web browser. To access the management software your computer must be able to “see” the Router. Your computer can see the Router if it is in the same “neighborhood” or subnet as the Router. This is accomplished by making sure your computer has IP settings that place it in the same subnet as the Router. The easiest way to make sure your computer has the correct IP settings is to configure it to use the DHCP server in the Router. The next section describes how to change the IP configuration for a computer running a Windows operating system to be a DHCP client. 2. Configure the WAN Connection Once your are able to access the configuration software you can proceed to change the settings required to establish the ADSL connection and connect to the service provider’s network. There are different methods used to establish the connection to the service provider’s network and ultimately to the Internet. You should know what Encapsulation and connection type you are required to use for your ADSL service. It is also possible that you must change the PVC settings used for the ADSL connection. Your service provider should provide all the information you need to configure the WAN connection. Configuring IP Settings on Your Computer In order to configure your system to receive IP settings from the Router it must first have the TCP/IP protocol installed. If you have an Ethernet port on your computer, it probably already has TCP/IP protocol installed. If you are using Windows XP the TCP/IP is enabled by default for standard installations. Below is an illustrated example of how to configure a Windows XP system to automatically obtain IP settings from the Router. Following this example is a step-by-step description of the procedures used on the other Windows operating systems to first check if the TCP/IP protocol has been installed, if it is not instruction are provided for installing it. Once the protocol has been installed you can configure the system to receive IP settings from the Router. For computers running non-Windows operating systems, follow the instructions for your OS that configure the system to receive an IP address from the Router, that is, configure the system to be a DHCP client. Note If you are using this Router to provide Internet access for more than one computer, you can use these instructions later to change the IP settings for the other computers. However you cannot use the same IP address since every computer must have its own IP address that is unique on the local network. 5 DSL-500G ADSL Router User’s Guide Configure Windows XP for DHCP Use the following steps to configure a computer running Windows XP to be a DHCP client. 1. 2. From the Start menu on your desktop, go to click on Control Panel. In the Control Panel folder, click on Network and Internet Connections. 6 DSL-500G ADSL Router User’s Guide 3. 4.

If the browser software on the computer you are using is configured to use a proxy server for Internet access, it is necessary to first disable the proxy connection. Check for Proxy service in Windows Internet Explorer: In Windows Internet Explorer, you can check if a proxy server is enabled using the following procedure: 1. In Windows, click on the START button, go to Settings and choose Control Panel. 2. In the Control Panel window, double-click on the Internet Options icon. 3. Click the Connections tab and click on the LAN Settings button. 4. Verify that the “Use proxy server” option is NOT checked. If it is checked, click in the checked box to deselect the option and click OK. To use the web-based management software, launch your web browser software and use the LAN IP address of the Router to access the management software. The default LAN IP address of the Router is used in the Address bar of your web browser window. Type in http:// followed by the default IP address, 10.1.1.1 in the address bar of the browser. The URL in the address bar should read: http://10.1.1.1 A new window appears prompting you for a user name and password needed to gain access the web configuration manager. Use the default user name: admin and password: admin for first time set up. You can change the password once you have established the ADSL connection. The user name and password allows any computer on the same subnet as the Router to access the web configuration manger. This password can also be used to Telnet to the device through the Ethernet or the Internet interfaces. To change this password, see the next chapter. Note Do not confuse the user name and password used to access the web-based manager with the ADSL account user name and password needed for PPP connections to access the ADSL or network service provider’s network. 12 DSL-500G ADSL Router User’s Guide The first web page you will see when you successfully login is the System View page. This page can be used later, once you have a connection established. For now however, the information contained here is not useful. The menu you need to establish the ADSL connection is the Quick Configuration menu. This menu is located in the Home folder located on the left hand side of your browser window. Open this folder by clicking on it twice. Web-based Manager Main Menu – First Time Log On In the Home folder you will see two hyperlinks, Home and Quick Configuration. You need to access the Quick Configuration menu; double-click on the hyperlink for this menu. Once you have accessed the menu you can change the Router’s configuration settings as instructed by your ISP. You will then need to save or “Submit” the settings to the flash memory of the Router. Finally you will use another menu to commit the new settings so they can be used by the Router, and restart the device. This last step is done in the Commit & Reboot menu. If you have been given special connection software to install on your computer, you can install it while the Router is rebooting. 13 DSL-500G ADSL Router User’s Guide Configure WAN Connection (ADSL Service Connection) Click on the Quick Configuration hyperlink to access the configuration settings you need to establish the ADSL connection. Quick Configuration Window When setting up the Router for the first time, use the Quick Configuration window and follow the steps below to change settings as instructed by your ISP. Some of the settings can be left at their default value depending on the requirements of the connection. Details about the settings listed here can be found in the next chapter. 1. PVC: Leave this set at the default value 0 the first time the Router is set up. For more information on this option see Multiple PVC Operation 2. Operation Mode: This also should be left at the default setting Enabled. This enables the PVC used for the initial connection. 3. Connection Type: Change connection method and packet encapsulation technique as instructed by your ISP. The available connection types are PPPoE LLC, PPPoE VC-Mux, PPPoA LLC, PPPoA VC-Mux, IPoA LLC, IPoA VC-Mux, Bridged IP LLC, Bridged IP VC-Mux, form the pull-down menu. Default Connection Type = PPPoE LLC. 4. VPI: If instructed to change this, type in the VPI value for the initial connection (using PVC 0). Default = 0. 5. VCI: If instructed to change this, type in the VCI value for the initial connection (using PVC 0). Default = 35. 6. Bridge: This may be left t the default setting Disabled. Some users may opt to enable this now by selecting Enabled from the drop-down menu. 7. IGMP: Leave this set to Disabled. 8. IP Address: & Subnet Mask: Some users may be required to configure the IP settings for the WAN connection. If you are using IPoA or a Bridged IP connection, you may be instructed by your ISP to enter your global IP settings. If you are told to enter an IP Address and Subnet Mask, enter ithem here. 14 DSL-500G ADSL Router User’s Guide 9. DNS Some users will be required to enter an IP address used for DNS services. If you are given a DNS server IP address enter that here along with a secondary or back-up DNS server IP address if you were given one. 10. For PPP connections (PPPoE or PPPoA), you must supply a User Name and Password used to verify the identity of your account. 11. If you entered a DNS server IP address (Step 9) leave this set to Enable. If you are not using DNS, select the Disable option. 12. When you have defined the Quick Configuration settings, click the Submit button to save the settings in temporary memory. These settings and all other configuration changes made to the Router must be Committed (to non-volatile memory) and the Router must be rebooted for the changes to go into effect. The Router will negotiate the ADSL connection automatically upon rebooting. Continue to the Commit & Reboot procedure. Commit & Reboot Commit and Reboot Menu To save current configuration settings as they have been submitted click the Commit button. A message informs you when the settings have been successfully committed to memory. You must now reboot the device to put the settings into effect. Make sure Reboot is selected in the Reboot Mode: pull-down menu and click . Do not reboot the device using the Reset button on the back panel of the Router to activate new changes. This button resets the device settings to the FACTORY default values. Any custom settings will be lost. IMPORTANT After the Router has rebooted it will begin to negotiate the ADSL connection for your account. This will normally take a few seconds. When the ADSL connection has been successfully established, the ADSL Link LED indicator will light steady green. If the ADSL Link indicator does not light after a minute or so access the web configuration manager an double check the settings. Note Some accounts use PPP connection software for their Internet service connection. If you have been given a CD with PPP software, install this now as instructed by your service provider. After the Router has rebooted it will negotiate the ADSL connection. For PPP (PPPoE and PPPoA) connections software is installed on the computer directly connected to the computer. This software is used to verify the identity of your account and establish a secure Point-to-Point connection to the service provider’s network infrastructure. 15 DSL-500G ADSL Router User’s Guide 4 Web Configuration Management Guide This chapter describes how to use the embedded web-based management software to configure the Router for additional PVC connection profiles, to change the LAN IP settings, to change the global WAN IP address and to perform other management functions. Manager Interface Layout The management software used for the Router initially presents the Home menu pictured below when you first log in. On the left side you see four folders, the hyperlinked Home folder contains the Quick Configuration menu. The LAN folder contains hyperlinked menus used for assigning LAN IP settings to the Router and IP services performed by the Router. The Bridging and Routing folders contain two of the same hyperlinked menus, the ATM VCC page and the EoA page. These are used to configure settings that allow the Router to operate on the service provider’s network. If you are using the Router for multiple virtual connections, these menus are also used to configure these additional virtual connections (PVCs). Figure 5. Router Web-based Quick Configuration Manager GUI Commonly Used Buttons The following buttons are used throughout the web management application. Stores in temporary system memory any changes you have made on the current page. Redisplays the current page with updated statistics or settings. On pages that display accumulated statistics, this button resets the statistics to their initial values. Launches the online help for the current topic in a separate browser window. Help is available from the main topic pages. 16 DSL-500G ADSL Router User’s Guide Quick Configuration The Quick Configuration displays the settings you are most likely to need to change when you first set up the Router. These settings are explained briefly below: ATM Interface Select the ATM interface you want to use (use atm-0 for a single ATM interface). Your system may be configured with more than one ATM interface if you are using different types of services with your ISP. See ATM VC Configuration. Operation Mode This setting enables or disables the device's Internet and routing functions. When set to "No", the device cannot be used to provide Internet connectivity for your network. Encapsulation This setting determines the type of data link used to communicate with your ISP. See ATM VC Configuration. VPI and VCI These settings determine the unique data path your modem uses to communicate with your ISP. See ATM VC Configuration. Bridge This setting enables or disables bridging between the device and your ISP. Your ISPs may also refer to this using "RFC 1483" or "Ethernet over ATM". See Bridging. IGMP This setting enables or disables the Internet Group Management Protocol, which some ISPs use to perform remote configuration of your device. IP Address and Subnet Mask If your ISP has assigned a public IP address to your LAN, enter the address and the associated subnet mask in the boxes provided. Check with your ISP to get this information. You may have to use the public IP address for your computer. In this case you do not enter the IP address here but configure these settings for your computer. Default Route When enabled, this setting specifies that the IP address specified above will be used as the default route for your LAN. Whenever, one of your LAN computers attempts to access the Internet, the data will be sent via the WAN interface. Gateway IP Address Specify the IP address that identifies the ISP server through which your Internet connection will be routed. Username and Password Enter the username and password you use to log in to your ISP. (Note: this is not the same as the user name and password you used to log in to Web Configuration Manager.) Use DNS Click Enable to turn on the DNS forwarding service, which forwards to your LAN PCs the Domain Name System server addresses that your PPP connection learns from your ISP. This option can only be used when the Router is configured to act as a DHCP server for your PCs. If you click Disable, you must configure DNS addresses manually on each PC or in the fields below.

System Mode Read-only, lists the current mode of operation for the device. Choose the source the Router uses to obtain its own IP settings for operation on the Ethernet LAN. By default the Router’s IP settings are set to Manual. Get LAN IP Address You may select External DHCP to use a DHCP server from outside the LAN. An external DHCP server will send DHCP settings through the WAN port. The external DHCP server may be part of the ISP’s network. The remaining alternative, Internal DHCP Server is used to obtain IP settings from a DHCP server within the Ethernet LAN. The IP settings will sent through the LAN port. The IP address your computers use to identify the device’s LAN port. LAN IP Address Note that the public IP address assigned to you by your ISP is not your LAN IP address. The public IP address identifies the WAN (ADSL) port on your Router to the Internet. Type in the IP address for the Ethernet LAN interface. Default = 10.1.1.1 LAN Network Mask The LAN Network mask identifies which parts of the LAN IP Address refer to your network as a whole and which parts refer specifically to nodes on the network. Type in the Subnet Mask for the Ethernet LAN IP interface. Default = 255.0.0.0 Click the Submit button to save the settings in temporary memory. If you are changing the IP address you will need to login again to access the web manager. If you are getting IP settings from DHCP, the new IP settings will be applied after you submit, commit and reboot. You must Commit & Reboot the device to save your changes to permanent memory. 19 DSL-500G ADSL Router User’s Guide DHCP Service Modes DHCP services can be employed in one of three different ways; it can provide DHCP services, it can receive DHCP services or it can relay DHCP service. By default the device is configured to act as a DHCP server on the Ethernet LAN. In this case it will supply IP settings to hosts that are configured to receive IP settings from a DHCP server. The device may also be configured to relay IP settings from your ISP’s DHCP server. In this case, you will want to configure the client hosts on your LAN to automatically obtain IP settings. Finally the Router can perform no DHCP function at all. In this case, it will need to be either manually assigned IP settings or receive them from a DHCP server on your LAN or from the ISP (see previous section). Figure 8. DHCP Mode Configuration Choose one the options below from the DHCP Mode: drop-down menu. DHCP Server This is the default mode for the Router. In this mode it provides DHCP services to properly configured hosts on the Ethernet LAN. DHCP Relay In this mode the Router is an intermediary device or relay agent between a DHCP server owned by the ISP and host systems on your LAN. none In this mode the device does deliver or relay any DHCP services. If you choose this option and are operating in Router mode you will need to supply IP settings to the device manually (see previous section). Click the Submit button to save the settings in temporary memory. When you are done making changes to the configuration settings, open the Commit & Reboot menu and click the Commit button to save your changes to permanent memory. 20 DSL-500G ADSL Router User’s Guide WAN Configuration Options If you are using the Router with two or more virtual connections (VC) one way to configure the additional connections is by using the WAN folder menus. You can use the ATM VC configuration menu to first create the additional VC. You may then need to create or modify a WAN interface using the PPP or IPoA configuration menus. ATM VC Configuration When computers access the Internet using the Router, data is exchanged with your network service provider or ISP through a complex network of telephone switches, Internet routers, servers, and other specialized hardware. These various devices communicate using a common language, or protocol, called Asynchronous Transfer Mode (ATM). On the Wide Area Network (WAN) that connects you to your ISP, the ATM protocol performs functions like those that the Ethernet protocol performs on your LAN. This section describes how to configure the ATM virtual channel connection (VCC). The VCC properties define the path the Router uses to communicate with your ISP over the ATM network. To view your current configuration, log into the Configuration Manager, and then click the ATM VCC button in the Bridging folder. The ATM VCC Configuration page displays, as shown below: Figure 9. ATM VCC Configuration Menu Additional Virtual Connections In order to use more than one PVC setting, it will be necessary to define one or two set of parameters for each virtual connection. First use the ATM VC Configuration menu to define new AAL5 settings. All additional PVCs must be added using the ATM VC menu. For connections that do not use PPPoE or PPPoA, it will also be necessary to use the EOA Configuration menu to establish Ethernet over ATM settings for the PVC adding in the ATM VC menu. To define AAL5 settings for a new virtual connection, click the Add button. To modify an existing AAL5 setting, click the pencil icon ( ) for that set. When you choose to add a new set or modify an existing set, a new menu appears (see below). To delete an existing AAL5 setting, click the trashcan ( ) for that set. 21 DSL-500G ADSL Router User’s Guide Figure 10. ATM VCC – Add (or Modify) Parameters To Add or Modify AAL5 Parameters define the following: VCC Interface The name of the lower-level interface on which this VC operates. The lowlevel interface names are pre-configured in the software and identify the type of traffic that can be supported, such as data or voice. Internet data services typically use an AAL5-type interface. If you are adding a new VCC Interface, choose the AAL5 set you want to define from the pull-down menu (Add menu only). VPI This setting (together with the VCI and Mux Type) identifies a unique ATM data path for communication between the Router and service provider. If you are adding a new VCC Interface or changing the existing VPI value, type in the new VPI value. VCI If you are adding a new VCC Interface or changing the existing VCI value, type in the new VCI value. Mux Type Select VC-Mux or LLC from pull-down menu. MAX Proto per AAL5 This setting indicates the number of higher-level interfaces that the VC can support (the higher level interfaces can be PPP, EoA, or IPoA interfaces). The Router supports up to eight however you must make arrangements your service provider for this additional service. Click the Submit button to save the settings in temporary memory. When you are done making changes to the configuration settings, open the Commit & Reboot menu and click the Commit button to save your changes to permanent memory. 22 DSL-500G ADSL Router User’s Guide PPP Configuration PPP is configured as a group of software settings associated with the ADSL port. Although the device has only one physical ADSL port, the Router can be defined with more than one group of PPP settings. Each group of settings is called a PPP interface and is given a name, such as ppp-0, ppp-1, etc. Figure 11. PPP Configuration You can configure the following settings on the PPP Configuration page: Inactivity TimeOut(mins): - The time in minutes that must elapse before a PPP connection times-out due to inactivity. Ignore WAN to LAN traffic while monitoring activity: - When enabled, data traffic traveling in the incoming direction -- from the WAN port to the LAN port -- will not count as activity on the WAN port; i.e., it will not prevent the connection from being terminated if it has been otherwise inactive for the specified time. To configure a new PPP interface click the Add button. A new menu appears. Figure 12. PPP Interface - Add 23 DSL-500G ADSL Router User’s Guide The PPP Configuration table displays the following fields: PPP Interface The PPP interface you are configuring. ATM VC The Virtual Circuit over which this PPP data is sent. The VC identifies the physical path the data takes to reach your ISP. The type of Firewall protections that are in effect on the interface. A public interface connects to the Internet (PPP interfaces are typically public). Packets received on a public interface are subject to the most restrictive set of firewall protections defined in the software. Interface Sec Type A private interface connects to your LAN, such as the Ethernet interface. Packets received on a private interface are subject to a less restrictive set of protections, because they originate within the network. The term DMZ (de-militarized zone), in Internet networking terms, refers to computers that are available for both public and in-network accesses (such as a company's public Web server). Protocol The type of PPP protocol used. Your ISP may use PPP-over-Ethernet (PPoE) or PPP-over-ATM (PPoA). Service Name This feature is available with PPoE interfaces but not with PPoA interfaces. The name of the ISP service you are using with this PPP connection. ISPs may offer different types of services (for example, for online gaming or business communications), each requiring a different login and other connection properties. Use DHCP When set to Enable, the device will acquire additional IP information from the ISP's DHCP server. The PPP connection itself acquires the device's IP address, mask, DNS address, and default gateway address. Use DNS When set to Enable, the DNS address learned through the PPP connection will be distributed to clients of the device's DHCP server. This option is useful only when the Router is configured to act as a DHCP Server for your LAN. When set to Disable, LAN hosts will use the DNS address(es) pre-configured in the DHCP pool. Default Route This indicates whether the Router should use the IP address assigned to this connection as its default route. It is Enabled by default and can be Disabled by selecting the appropriate option. Security Protocol Protocol used to confirm the identity of the subscriber. Login Name The name you use to log in to your ISP each time this PPP connection is established. Login Password The password you use to log in to your ISP each time this PPP connection is established. 24 DSL-500G ADSL Router User’s Guide IpoA Configuration The IPoA table contains a row for each EOA interface currently defined on the device. The table may initially contain no entries. Figure 13. IPoA Configuration The IPoA Configuration table displays the following fields: IPoA Interface The IPoA interface you are configuring. Conf. IP Address The IP address you want to assign to the interface. The type of Firewall protections that are in effect on the interface. A public interface connects to the Internet (PPP interfaces are typically public). Packets received on a public interface are subject to the most restrictive set of firewall protections defined in the software. Interface Sec Type A private interface connects to your LAN, such as the Ethernet interface. Packets received on a private interface are subject to a less restrictive set of protections, because they originate within the network. The term DMZ (de-militarized zone), in Internet networking terms, refers to computers that are available for both public and in-network accesses (such as a company's public Web server). Netmask The netmask you want to assign to the interface. RFC 1577 Specifies whether the IPoA protocol to be used complies with the IEFT specification named "RFC 1577 - Classical IP and ARP over ATM" (contact your ISP if unsure). Default Route This indicates whether the Router should use the IP address assigned to this connection as its default route. It is Enabled by default and can be Disabled by selecting the appropriate option. Gateway IP Address The external IP address that the Router communicates with via the IPoA interface to gain access to the Internet. This is typically an ISP server.

Click the Commit button to save your changes to permanent memory. 26 DSL-500G ADSL Router User’s Guide EOA Configuration Ethernet-over-ATM (EOA) is a commonly used protocol for data transfer between Ethernet LANs and wide area networks that use the ATM protocol. Telecommunications industry networks often use the ATM in the within the their primary infrastructure or backbone. Network service providers that sell DSL services often use the EOA protocol for data transfer with their customers’ DSL Routers. EOA is implemented to create a bridged connection between a DSL Router and the ISP. In a bridged connection, data is shared between the ISP’s network and their customer’s as if the networks were on the same physical LAN. Bridged connections do not use the IP protocol. EOA can also be configured to provide a routed connection with the ISP, which uses the IP protocol to exchange data. This section describes how to configure an Ethernet-over-ATM interface on the Router, if one is needed to communicate with your ISP. Before creating an EOA interface or modifying the default settings, contact your ISP to determine which type of protocol they use. IMPORTANT Your ISP may use a protocol other than EOA for communication with the Router, such as the point-to-point protocol (PPP). One type of PPP, named PPP over Ethernet (PPPoE), actually works “on top” of the EOA protocol. The other type, PPP over ATM (PPPoA), does not. However, if your ISP uses either type of PPP, you do not need to separately create an EOA interface. If your service provider has given you PPP software for installation on your computer, follow the instructions given to you by your ISP and do not change the EOA settings. To view your current EOA configuration, log into the Configuration Manager, click the EoA button in the Bridging folder, the EOA Configuration page appears: Figure 15. EOA Configuration To define EOA settings for a new virtual connection, click the Add button. To modify an existing EOA setting, click the pencil icon ( ) for that set. When you choose to add a new set or modify an existing set, a new menu appears (see below). To delete an existing AAL5 setting, click the trashcan ( ) for that set. 27 DSL-500G ADSL Router User’s Guide Figure 16. EOA Interface – Modify To Add or Modify AAL5 Parameters define the following: EOA Interface Conf. IP Address: Net Mask: Use DHCP: This is used (by the Router) to identify the EOA interface. If you are adding a new EOA interface, choose the EOA set you want to define from the pull-down menu (Add menu only). The IP address assigned to the interface. If the interface will be used as a simple bridge to your ISP, then you do not need to specify IP information. If you enable DHCP for this interface, then the Configured IP address will serve only as a request to the DHCP server. The actual address that is assigned by the ISP may differ if this address is not available. Some ISPs use static IP settings that are manually assigned to each account. If your service provider instructs you to configure a Static IP Address, type in the global IP Address for this EOA interface. If you are assigned a Static IP Address and Net Mask, type in the Net Mask for this EOA interface. When checked, this setting instructs the device to accept IP information assigned dynamically by your ISP’s DHCP server. If the interface will be used for bridging with your ISP, leave this checkbox unselected. Select Enable or Disable for DHCP service. Click the Submit button to save the settings in temporary memory. When you are done making changes to the configuration settings, open the Commit & Reboot menu and click the Commit button to save your changes to permanent memory. 28 DSL-500G ADSL Router User’s Guide Bridge Configuration The Router can be configured to act as a bridging device between your LAN and your ISP. Bridges are devices that enable two or more networks to communicate as if they are two segments of the same physical LAN. This section describes how to configure the Router to operate as a bridge. Before changing the bridge configuration, check with your ISP to determine the type of connection used to exchange data with their client’s DSL Routers (such as Ethernet bridging). IMPORTANT A bridge is a device used to connect two or more networks. A bridge device is able to learn the unique manufacturer-assigned hardware identifier (MAC Address) of each computer or device on either or both networks to which it is connected. It learns that some of the MAC addresses represent computers attached via one of the device's interfaces and other MACs represent computers connected via other interfaces. For example, the MAC addresses of your home computers are learned through (or associated with) the Ethernet port, and the MACs of your ISP's computers are attached via the WAN (DSL) port. It stores the MAC addresses and the interface associated with each MAC in its bridge forwarding table. When the bridge receives a data packet, it compares its destination MAC to the entries in the bridge forwarding table. When the packet's destination MAC address matches one of the entries, it forwards the packet through the interface that connects to the corresponding network. The bridge does not send the data directly to the receiving computer, but broadcasts it to the receiving network, making it available to any node on that network. On the receiving network, the packet is delivered in a form recognized by the network protocol (Ethernet for the LAN side of the Router) and delivered to its destination. When the bridge does not recognize a packet’s destination MAC address, it broadcasts the packet through all of its interfaces – to both networks. You may need to use the device as a bridge if: Your ISP uses protocols that require bridging with your LAN. The device can be configured to appear as a bridge when communicating with your ISP, while continuing to provide router functionality for your LAN. Your LAN may include computers that communicate using "layer-3" protocols other than the Internet Protocol. These include IPX® and AppleTalk®. In this case, the device can be configured to act as a bridge for packets that use these protocols while continuing to serve as a router for IP data. 29 DSL-500G ADSL Router User’s Guide To add or change bridge configuration settings, log into the Configuration Manager and click on the Bridging button in the Bridging folder. Figure 17. Bridge Configuration Menu To define Bridge settings for a new virtual connection, click the Add button. When you choose to add a new set or modify an existing set, a new menu appears (see below). To delete an existing setting, click the trashcan ( ) for that set. To enable bridging, you simply specify the device interfaces on which you want to bridge data, and then enable bridging mode by clicking the Enable option. Click the Submit button to save the settings in temporary memory. When you are done making changes to the configuration settings, open the Commit & Reboot menu and click the Commit button to save your changes to permanent memory. If you enable bridging on an interface that has already been assigned an IP address, then it is considered IP-enabled and will route (rather than bridge) IP packets received on the interface. The interface will bridge non-IP data it receives, however. Note You can determine whether the Ethernet (eth-0 interface has been assigned an IP address by displaying the IP Address Table (display the Routing tab, then click IP Addr). These interfaces will display in the table only if they have been assigned IP addresses. You can check whether the eoa-0 interface has been assigned an IP address by displaying the EOA configuration table (display the WAN tab, and then click EOA). If the Config IP Address field is empty and the Use DHCP field contains the word Disable, then no IP address has been assigned. 30 DSL-500G ADSL Router User’s Guide Routing Configuration Links to the IP Route and IP Address tables are found within the Routing folder. The remaining links are duplicate links to menus that have been previously described. IP Route IP Routes are used to define gateways and hops used to route data traffic. Most users will not need to use this feature as the previously configured default gateway and LAN IP settings on your host computers should be sufficient. You may need to define routes if your LAN includes two or more networks or subnets, if you connect to two or more ISP services, or if you connect to a remote corporate LAN. Use the IP Route Table to Add new IP routes. The new IP routes are in effect additional rules used by the Router for routing data. See the next section, Adding IP Routes for instructions. Figure 18. IP Route Table Information displayed in the IP Route Table is summarized below: Destination Netmask Next Hop IF Name Route Type Route Origin Specifies the IP address of the destination computer. The destination can specified as the IP address of a specific computer or an entire network. It can also be specified as all zeros to indicate that this route should be used for all destinations for which no other route is defined (this is the route that creates the default gateway). Indicates which parts of the destination address refer to the network and which parts refer to a computer on the network. The default gateway uses a netmask of 0.0.0.0. Specifies the next IP address to send data to when its final destination is that shown in the destination column. Displays the name of the interface through which to data is forwarded to the specified next hop. Displays whether the route is direct or indirect. In a direct route, the source and destination computers are on the same network, and the router attempts to directly deliver the data to the computer. In an indirect route, the source and destination computers are on different networks, and the router forwards data to a device on another network for further handling. Displays how the route was defined. Dynamic indicates that the route was predefined on the system by your ISP or the manufacturer. Routes you create are labeled Local. Other routes can be created automatically, or defined remotely through various network management protocols (LCL or ICMP). 31 DSL-500G ADSL Router User’s Guide Adding IP Routes To add an IP route to the device's routing table, follow these steps: 1. Click the Add button to display the IP Route – Add menu. 2. Type in the destination, network mask, and gateway or next hop for this route. To create a route that defines the device's default gateway, enter 0.0.0.0 in both the Destination and Net Mask fields. Enter your ISP's IP address in the Gateway/NextHop field. 3. Click the Submit button. A page will display to confirm your changes. 4. Click the Close button to return to the IP Route table page. The new route should display in the table. 5. Display the Admin tab, and click Commit & Reboot in the task bar. 6. Click Commit button to save your changes to permanent memory. IP Address The IP Address Table lists the IP addresses, network masks ("Net Mask"), and interface names ("IF Name") for each of its IP-enabled interfaces. Figure 19. IP Address Table The listed IP addresses include: The IP address of the device's Ethernet LAN port (eth-0). The IP address of the WAN interface (ppp-0, eoa-0, or ipoa-0 depending on the connection protocol). This is the address that your ISP and other external devices use to identify your network. Your ISP may assign the same address each time, or it may change each time you reconnect. The "loopback" IP address, named lo-0, of 127.0.0.1. This is a special address that enables the device to keep any data addressed directly to it, rather than route the data through the WAN or LAN ports. If your device has additional interfaces, the IP addresses of these will also display. 32 DSL-500G ADSL Router User’s Guide NAT Network Address Translation is a method for disguising the private IP addresses you use on your LAN as the public IP address you use on the Internet. You define NAT rules that specify exactly how and when to translate between public and private IP addresses. NAT is enabled by default. You can enable or disable NAT by selecting the Enable or Disable option in the configuration menu and submitting the settings. Figure 20. NAT Configuration To view the NAT Rule setting menu or the NAT Translations entries, select the option from the NAT Options: drop-down menu. To configure NAT Rules, select the NAT Rule Entry option and click the Add button. A new window is displayed: Figure 21. Add NAT Rule From the Rule Flavor drop-down list, select Basic, Filter, NAPT, BIMAP, RDR or PASS. The page redisplays with only the fields that are appropriate for the chosen NAT flavor. 33 DSL-500G ADSL Router User’s Guide Enter information appropriate to the NAT flavor. The information in the various menus is summarized in the table below. Rule ID IF Name Protocol Local Address From Local Address To Global Address From The Rule ID determines the order in which rules are invoked (the lowest numbered rule is invoked first, and so on). In some cases, two or more rules may be defined to act on the same set of IP addresses. Be sure to assign the Rule ID so that the higher priority rules are invoked before lower-priority rules. It is recommended that you select rule IDs as multiples of 5 or 10 so that, in the future, you can insert a rule between two existing rules. Once a data packet matches a rule, the data is acted upon according to that rule and is not subjected to higher-numbered rules. Typically, NAT rules are used for communication between your LAN and the Internet. Because the device uses the WAN interface (which may be named ppp-0, eoa-0, or ipoa-0) to connect your LAN to your ISP, it is the usual IF Name selection. This selection specifies which type of Internet communication will be subject to this translation rule. You can select ALL if the rule applies to all data. Or, select TCP, UDP, ICMP, or a number from 1-255 that represents the IANA-specified protocol number. Type the starting IP of the range of private address you want to be translated. You can specify that data from all LAN addresses should be translated by typing 0 (zero) in each From field and 255 in each To field. Or, type the same address in both fields if the rule only applies to one LAN computer. Type the ending IP of the range of private address you want to be translated. Type the public IP address assigned to you by your ISP. If you have multiple WAN interfaces, in both the Global Address From and Global Address To fields, type the IP address of the interface to which this rule applies. This rule will not be enforced for data that arrives on other PPP interfaces. Global Address To If you have multiple WAN interfaces and want the rule to be enforced on a range of them, type the starting and ending IP addresses of the range. You can specify a single value by entering that value in both the From and To fields. Specify a range of destination addresses if you want this rule to apply only to Destination outbound traffic to addresses in that range. Address (or If you enter only the network ID portion of the destination address, then the rule addresses)* will apply to outbound traffic to all computers on network. You can specify a single value by entering that value in both the From and To fields. Specify a range of destination ports if you want this rule to apply to any outbound traffic to the types of servers identified by that port number. For example, if you do not specify a destination address, but specify a Destination Port From/To of 21, then this translation will occur on all accesses Destination Port (or by your LAN to all external FTP servers (that is, when one of your LAN ports)* computers communicates with an external FTP server, the source IP address in the packet headers is changed to the public address, replacing the initiator's private IP address). Common port numbers include: 21-FTP (file transfer protocol) server 25-SMTP (simple mail transfer protocol) server 80-HTTP (World Wide Web) server. * Specify both a destination address (or range) and a destination port (or range) if you want this translation rule to apply to accesses to the specified server type at the specified IP address or network. 34 DSL-500G ADSL Router User’s Guide RIP RIP is an Internet protocol you can set up to share routing table information with other routing devices on your LAN, at your ISP's location, or on remote networks connected to your network via the ADSL line. Figure 22. RIP Configuration Most small home or office networks do not need to use RIP; they have only one router and one path to an ISP. In these cases, there is no need to share routes, because all routes from the network go to the same ISP gateway. You may want to configure RIP if any of the following circumstances apply to your network: • Your home network setup includes an additional router or RIP-enabled PC. The DSL-500G and your second router will need to communicate via RIP to share their routing tables. • Your network connects via the ADSL line to a remote network, such as a corporate network. In order for the networks at the two sites to share the routes used internally within each LAN, they should both be configured with RIP. • Your ISP requests that you run RIP for communication with devices on their network. To change RIP configuration: 1. If necessary, change the Age and Update Time. These are global settings for all interfaces that use RIP. Age is the amount of time in seconds that the device's RIP table will retain each route that it learns from adjacent computers. Update Time specifies how frequently the Router will send out its routing table its neighbors. 2. In the IF Name column, select the name of the interface on which you want to enable RIP. For communication with RIP-enabled devices on your LAN, select eth-0 or the name of the appropriate virtual Ethernet interface. For communication with your ISP or a remote LAN, select the corresponding ppp, eoa, or other WAN interface. 3. Select a metric value for the interface. 4. RIP uses a "hop count" as a way to determine the best path to a given destination in the network. The hop count is the sum of the metric values assigned to each port through which data is passed before reaching the destination. Among several alternative routes, the one with the lowest hop count is considered the fastest path. For example, if you assign this port a metric of 1, then RIP will add 1 to the hop count when calculating a route that passes through this port. If you know that communication via this interface is slower than through other interfaces on your network, you can assign it a higher metric value than the others. You can select any integer from 1 to 15. 35 DSL-500G ADSL Router User’s Guide 5. Select a Send Mode and a Receive Mode. The Send Mode setting indicates the RIP version this interface will use when it sends its route information to other devices. The Receive Mode setting indicates the RIP version(s) in which information must be passed to the Router in order for it to be accepted into its routing table. RIP version 1 is the original RIP protocol. Select RIP1 if you have devices that communicate with this interface that understand RIP version 1 only. RIP version 2 is the preferred selection because it supports "classless" IP addresses (which are used to create subnets) and other features. Select RIP2 if all other routing devices on your LAN support this version of the protocol. 6. Click the Add button. The new RIP entry will display in the table. 7. Click the Enable radio button to enable the RIP feature. 8. Click the Submit button to save the settings in temporary memory. When you are done making changes to the configuration settings, open the Commit & Reboot menu and click the Commit button to save your changes to permanent memory. Firewall The Firewall enables you to protect the system against denial of service (DoS) attacks and other types of malicious accesses to your LAN. You can also specify how to monitor attempted attacks, and who should be automatically notified. Figure 23. Firewall Configuration 36 DSL-500G ADSL Router User’s Guide Follow these instructions to configure global firewall settings: Configure any of the following settings that display in the Firewall Global Information table: Black List Status: If you want the device to maintain and use a black list, click Enable. Click Disable if you do not want to maintain a list. Black List Period(min): Specifies the number of minutes that a computer's IP address will remain on the black list (i.e., all traffic originating from that computer will be blocked from passing through any interface on the Router). For more information, see Managing the Black List below. Attack Protection: Click the Enable radio button to use the built-in firewall protections that prevent the following common types of attacks: IP Spoofing: Sending packets over the WAN interface using an internal LAN IP address as the source address. Tear Drop: Sending packets that contain overlapping fragments. Smurf and Fraggle: Sending packets that use the WAN or LAN IP broadcast address as the source address. Land Attack: Sending packets that use the same address as the source and destination address. Ping of Death: Illegal IP packet length. DoS Protection: Click the Enable radio button to use the following denial of service protections: SYN DoS ICMP DoS Per-host DoS protection Max Half open TCP Connection: Sets the percentage of concurrent IP sessions that can be in the halfopen state. In ordinary TCP communication, packets are in the half-open state only briefly as a connection is being initiated; the state changes to active when packets are being exchanged, or closed when the exchange is complete. TCP connections in the half-open state can use up the available IP sessions. If the percentage is exceeded, then the half-open sessions will be closed and replaced with new sessions as they are initiated. Max ICMP Connection: Sets the percentage of concurrent IP sessions that can be used for ICMP messages. If the percentage is exceeded, then older ICMP IP sessions will be replaced by new sessions as the are initiated. Max Single Host Connection: Sets the percentage of concurrent IP session that can originate from a single computer. This percentage should take into account the number of hosts on the LAN. Log Destination: Specifies how attempted violations of the firewall settings will be tracked. Records of such events can be sent via Ethernet to be handled by a system utility Ethernet to (Trace) or can emailed to specified administrators. E-mail ID of Admin 1/2/3: Specifies the e-mail addresses of the administrators who should receive notices of any attempted firewall violations. Type the addresses in standard internet e-mail address format. The e-mail message will contain the time of the violation, the source address of the computer responsible for the violation, the destination IP address, the protocol being used, the source and destination ports, and the number violations occurring the the previous 30 minutes. If the ICMP protocol were being used, then instead of the source and destination ports, the e-mail will report the ICMP code and type. Click the Submit button to save the settings in temporary memory. When you are done making changes to the configuration settings, open the Commit & Reboot menu and click the Commit button to save your changes to permanent memory. Managing the Black List If data packets are received that violate the firewall settings or any of the IP Filter rules, then the source IP address of the offending packets can be blocked from such accesses for a specified period of time. You can enable or disable use of the black list using the settings described above. The source computer remains on the black list for the period of time that you specify. To view the list of currently blacklisted computers, click the Black List button at the bottom of the Firewall Configuration page. The table displays the following information for each entry: 37 DSL-500G ADSL Router User’s Guide Host IP Address: The IP address of the computer that sent the packet(s) that caused the violation Reason: A short description of the type of violation. If the packet violated an IP Filter rule, the custom text from the Log Tag field will display. IPF Rule ID: If the packet violated an IP Filter rule, this field will display the ID assigned to the rule. The IP filter feature enables you to create rules that control the forwarding of incoming and outgoing data between your LAN and the Internet and within your LAN. This topic explains how to create IP filter rules. IP Filter The IP Filter Configuration page displays global settings that you can modify, and the IP Filter rule table, which shows all currently established rules. Figure 24. IP Filter Configuration The IP Filter Configuration page enables you to configure the following IP filter global settings. Security Level: This setting determines which IP Filter rules take effect, based on the security level specified in each rule. For example, when High is selected, only those rules that are assigned a security value of High will be in effect. The same is true for the Medium and Low settings. When None is selected, IP Filtering is disabled. Private/Public/DMZ Default Action: This setting specifies a default action to be taken (Accept or Deny) on private, public, or DMZ-type device interfaces when they receive packets that do not match any of the filtering rules. You can specify a different default action for each interface type. (You specify an interface's type when you create the interface; see the PPP configuration page, for example.) • A public interface typically connects to the Internet. PPP, EoA, and IPoA interfaces are typically public. Packets received on a public interface are subject to the most restrictive set of firewall protections defined in the software. Typically, the global setting for public interfaces is Deny, so that all accesses to your LAN initiated from external computers are denied (discarded at the public interface), except for those allowed by a specific IP Filter rule. 38 DSL-500G ADSL Router User’s Guide • A private interface connects to your LAN, such as the Ethernet interface. Packets received on a private interface are subject to a less restrictive set of protections, because they originate within the network. Typically, the global setting for private interfaces is Accept, so that LAN computers have access to the Routers' Internet connection. The term DMZ (de-militarized zone), in Internet networking terms, refers to computers that are available for both public and in-network accesses (such as a company's public Web server). Packets received on a DMZ interface -whether from a LAN or external source -- are subject to a set of protections that is in between public and private interfaces in terms of restrictiveness. The global setting for DMZ-type interfaces may be set to Deny so that all attempts to access these servers are denied by default; the administrator may then configure IP Filter rules to allow accesses of certain types. Adding an IP Filter Rule To create an IP filter rule, you set various criteria that must be met in order for the rule to be invoked. Use these instructions to add a new IP filter rule: 1. On the main IP Filter page, click the Add button to display the IP Filter Rule - Add page. Figure 25. IP Filter Rule - Add 2. Enter or select data for each field that applies to your rule. The following table describes the fields: Rule ID: Each rule must be assigned a sequential ID number. Rules are processed from lowest to highest on each data packet, until a match is found. It is recommended that you assign rule IDs in multiples of 5 or 10 (e.g., 10, 20, 30) so that you leave enough room between them for inserting a new rule if necessary. Action: Specifies what the rule will do to a packet when the packet matches the rule criteria. The action can be Accept (forward to destination) or Deny (discard the packet). Direction: Specifies whether the rule should apply to data packets that are incoming or outgoing on the selected interface. Incoming refers to packets coming in to the LAN on the interface, and Outgoing refers to packets going out from the LAN. You can use rules that specify the incoming direction to restrict external computers from accessing your LAN. 39 DSL-500G ADSL Router User’s Guide Interface: The interface on the device on which the rule will take effect. In Interface: The interface from which packets must have been forwarded to the interface specified in the previous selection. This option is valid only on rules defined for the outgoing direction. Log Option: When Enabled is selected, a log entry will be created on the system each time this rule is invoked. The log entry will include the time of the violation, the source address of the computer responsible for the violation, the destination IP address, the protocol being used, the source and destination ports, and the number violations occuring the the previous x minutes. (Logging may be helpful when troubleshooting.) This information can also be e-mailed to administrators. Security Level: The security level that must be enabled globally for this rule to take affect. A rule will be active only if its security level is the same as the globally configured setting (shown on the main IP Filter page). For example, if the rule is set to Medium and the global firewall level is set to Medium, then the rule will be active; but if the global firewall level is set to High or Low, then the rule will be inactive. Black List Status: Specifies whether or not a violation of this rule will result in the offending computer's IP address being added to the Black List, which blocks the Router from forwarding packets from that source for a specified period of time. Log Tag: A description of up to 16 characters to be recorded in the log in the event that a packet violates this rule. Be sure to set the Log Option to Enable if you configure a Log Tag. Start/End Time: The time range during which this rule is to be in effect, specified in military units. Src IP Address: IP address criteria for the source computer(s) from which the packet originates. In the drop-down list, you can configure the rule to be invoked on packets containing: • any: any source IP address. • lt: any source IP address that is numerically less than the specified address. • lteq: any source IP address that is numerically less than or equal to the specified address. • gt: any source IP address that is numerically greater than the specified address. • eq: any source IP address that is numerically equal to the specified address. • neq: any source IP address that is not equal to the specified address. • range: any source IP address that is within the specified range, inclusive. • out of range: any source IP address that is outside the specified range. • self: the IP address of the Router interface on which this rule takes effect. Dest IP Address: IP address rule criteria for the destination computer(s) (i.e., the IP address of the computer to which the packet is being sent). In addition to the options described for the Src IP Address field, the following option is available: • bcast: specifies that the rule will be invoked for any packets sent to the broadcast address for the receiving interface. (The broadcast address is used to send packets to all hosts on the LAN or subnet connected to the specified interface.) When you select this option, you do not need to specify the address, so the address fields are dimmed. Protocol: IP protocol criteria that must be met for rule to be invoked. You can specify that packets must contain the selected protocol (eq), that they must not contain the specified protocol (neq), or that the rule can be invoked regardless of the protocol (any). TCP, UDP, and ICMP are commonly used IP protocols; others can be identified by number, from 0-255, as defined by the Internet Assigned Numbers Authority (IANA). Store State: If this option is enabled, then stateful filtering is performed and the rule is also applied in the other direction on the given interface during an IP session. Source Port: Port number criteria for the computer(s) from which the packet originates. This field will be dimmed (unavailable for entry) unless you have selected TCP or UDP as the protocol. See the description of Src IP Address for the selection options. Dest Port: Port number criteria for the destination computer(s) (i.e., the port number of the type of computer to which the packet is being sent). This field will be dimmed (unavailable for entry) unless you have selected TCP or UDP as the protocol. See the description of Src IP Address for the selection options. 40 DSL-500G ADSL Router User’s Guide TCP Flag: Specifies whether the rule should apply only to TCP packets that contain the synchronous (SYN) flag, only to those that contain the non-synchronous (NOT-SYN) flag, or to all TCP packets. This field will be dimmed (unavailable for entry) unless you selected TCP as the protocol. ICMP Type: Specifies whether the value in the type field in ICMP packet headers will be used as a criteria. The code value can be any decimal value from 0-255. You can specify that the value must equal (eq) or not equal (neq) the specified value, or you can select any to enable the rule to be invoked on all ICMP packets. This field will be dimmed (unavailable for entry) unless you specify ICMP as the protocol. ICMP Code: Specifies whether the value in the code field in ICMP packet headers will be used as a criteria. The code value can be any decimal value from 0-255. You can specify that the value must equal (eq) or not equal (neq) the specified value, or you can select any to enable the rule to be invoked on all ICMP packets. This field will be dimmed (unavailable for entry) unless you specify ICMP as the protocol. IP Frag Pkt: Determines how the rule applies to IP packets that contain fragments. You can choose from the following options: • Yes: The rule will be applied only to packets that contain fragments. • No: The rule will be applied only to packets that do not contain fragments. • Ignore: (Default) The rule will be applied to packets whether or not they contain fragments, assuming that they match the other criteria. IP Option Pkt: Determines whether the rule should apply to IP packets that have options specified in their packet headers. • Yes: The rule will be applied only to packets that contain header options. • No: The rule will be applied only to packets that do not contain header options. • Ignore: (Default) The rule will be applied to packets whether or not they contain header options, assuming that they match the other criteria. Packet Size: Specifies that the IP Filter rule will take affect only on packets whose size in bytes matches this criteria. (lt = less than, gt = greater than, lteq = less than or equal to, etc.) TOD Rule Status: The Time of Day Rule Status determines how the Start Time/End Time settings are used. 3. • Enable: (Default) The rule is in effect for the specified time period. • Disable: The rule is not in effect for the specified time period, but is effective at all other times. When you are done selecting criteria, ensure that the Enable radio button is selected at the top of the page, and then click the Submit button at the bottom of the page. After a confirmation page displays, the IP Filter - Configuration page will redisplay with the new rule showing in the table. If the security level of the rule matches the globally configured setting, a green ball in the Status column for that rule, indicating that the rule is now in effect. A red ball will display when the rule is disabled or if its security level is different than the globally configured level. 7. Ensure that the Security Level and Private/Public/DMZ Default Action settings on the IP Filter Configuration page are configured as needed, then click the Submit button. A page displays to confirm your changes. 8. Click the Submit button to save the settings in temporary memory. When you are done making changes to the configuration settings, open the Commit & Reboot menu and click the Commit button to save your changes to permanent memory. 41 DSL-500G ADSL Router User’s Guide DNS Multiple DNS addresses are useful to provide alternatives when one of the servers is down or is encountering heavy traffic. ISPs typically provide primary and secondary DNS addresses, and may provide additional addresses. Figure 26. DNS Configuration Your LAN PCs learn these DNS addresses in one of the following ways: • Statically: If your ISP provides you with their DNS server addresses, you can assign the addresses to each PC by modifying the PCs' IP properties. • Dynamically from a DHCP pool: You can configure the DHCP Server feature on the Router and create an address pool that specify the DNS addresses to be distributed to the PCs. In either case, you can specify the actual addresses of the ISP's DNS servers (on the PC or in the DHCP pool), or you can specify the address of the LAN port on the Router (e.g., 10.1.1.1). When you specify the LAN port IP address, the device performs DNS relay. Configuring DNS Relay When you specify the device's LAN port IP address as the DNS address, then the Router automatically performs DNS relay; i.e., because the device itself is not a DNS server, it forwards domain name lookup requests that it receives from LAN computers to a DNS server at the ISP. It then relays the DNS server's response to the PC. When performing DNS relay, the device must maintain the IP addresses of the DNS servers it contacts. It can learn these addresses in either or both of the following ways: • Learned through PPP: If the device uses a PPP connection to the ISP, the primary and secondary DNS addresses can be learned via the PPP protocol. To use this method, the "Use DNS" checkbox must be selected in the PPP interface properties. (You cannot change this property by modifying an existing PPP interface; you must delete the interface and recreate it with the new setting.) Using this option provides the advantage that you will not need to reconfigure the PCs or the Router if the ISP changes their DNS addresses. • Configured on the Router: You can use the device's DNS feature to specify the ISP's DNS addresses. If the device also uses a PPP interface with the "Use DNS" property enabled, then these configured addresses will be used in addition to the two addresses learned through PPP. If "Use DNS" is not enabled, or if a protocol other than PPP is used (such as EoA), then these configured addresses will be used as the primary and secondary DNS addresses. 42 DSL-500G ADSL Router User’s Guide Follow these steps to configure DNS relay: 1. Configure the LAN PCs to use the Router's LAN IP address as their DNS server address -- by assigning the LAN IP address statically to each PC, or by inputting the LAN IP address or the address 0.0.0.0 as the DNS address in a DHCP server pool. 2. If using a PPP connection to the ISP, configure it to "Use DNS" so that the DNS server addresses it learns are used for DNS relay. --OR-- If not using a PPP connection (or if you want to specify DNS addresses in addition to those learned through PPP), configure the DNS addresses on the Router as follows: a. Click the Services tab, and then click DNS in the task bar. The DNS Configuration page displays. b. Type the IP address of the DNS server in an empty row and click the Add button. You can enter only two addresses. c. Click the Enable radio button, and then click the Submit button. 3. Click the Submit button to save the settings in temporary memory. When you are done making changes to the configuration settings, open the Commit & Reboot menu and click the Commit button to save your changes to permanent memory. 43 DSL-500G ADSL Router User’s Guide Blocked Protocols The Router is capable of sending and receiving information in a variety of protocol formats. The Blocked Protocols feature enables you to prevent the Router from passing any data that uses a particular protocol. Unlike the IP Filter feature, you cannot specify additional criteria for blocked protocols, such as particular users or destinations. However, when you are certain that a particular protocol is not needed or wanted on your network, this feature provides a convenient way to discard such data before it is passed. Figure 27. Blocked Protocols The following list describes each of the listed protocols. • PPOE: Point to Point Protocol over Ethernet. Many DSL modems use PPoE to establish and maintain a connection with a service provider. PPoE provides a means of logging in to the ISPs servers so that they can authenticate you as a customer and provide you access to the Internet. Check with your ISP before blocking this protocol. • IP Multicast: IP Multicast is an extension to the IP protocol. It enables individual packets to be sent to multiple hosts on the Internet, and is often used for handling e-mail mailing lists and teleconferencing/videoconferencing. • RARP: Reverse Address Resolution Protocol. This IP protocol provides a way for computers to determine their own IP addresses when they only know their hardware address (i.e., MAC addresses). Certain types of computers, such as diskless workstations, must use RARP to determine their IP address before communicating with other network devices. • AppleTalk®: A networking protocol used in for Apple Macintosh® networks. • NetBEUI: NetBIOS Enhanced User Interface. On many LAN operating systems, the NetBEUI protocol provides the method by which computers identify themselves to and communicate with each other. • IPX: Internetwork Packet Exchange. A networking protocol used on Novell Netware ®-based LANs. • BPDU: Bridge Protocol Data Unit. BPDUs are data messages that are exchanged across the switches between LANs that are connected by a bridge. BPDU packets contain information on ports, addresses, priorities and costs, and are exchanged across bridges to detect and eliminate loops in a network. • ARP: Address Resolution Protocol. Computers on a LAN use ARP to learn the hardware addresses (i.e., MAC addresses) of other computers when they know only their IP addresses. 44 DSL-500G ADSL Router User’s Guide • IPV6 Multicast: IP Multicasting under IP Protocol version 6. See IP Multicast above. • 802.1.Q: This IEEE specification defines a protocol for virtual LANs on Ethernet networks. A virtual LAN is a group of PCs that function as a local area network, even though the PCs may not be physically connected. They are commonly used to facilitate administration of large networks. To block a protocol, click the appropriate check box, and click the Submit button to save the settings in temporary memory. When you are done making changes to the configuration settings, open the Commit & Reboot menu and click the Commit button to save your changes to permanent memory. Changing the Manager Password The first time you log into the Web Configuration Manager, use the default user ID and password (admin and admin). The system allows only one user ID and password. Only the password can be changed. Access the User Configuration menu in the Admin folder. Figure 28. Change User Password To change user name and password used for management privileges, log into the Configuration Manager, click on the Add button and change these settings in a new window: User ID: This lists the current User ID (user name). New Password: Type in the new password. Confirm New: Type in the new password a second time for confirmation. Click the Submit button to save the settings in temporary memory. When you are done making changes to the configuration settings, open the Commit & Reboot menu and click the Commit button to save your changes to permanent memory. 45 DSL-500G ADSL Router User’s Guide Commit & Reboot Whenever you use the Web Configuration Manager to change system settings, the changes are initially placed in temporary storage (called random access memory or RAM). Your changes are made effective when you submit them, but will be lost if the device is reset or turned off. To save your changes for future use, you can use the commit function. This function saves your changes from RAM to permanent storage (called flash memory). Note When you Submit changes, they are activated immediately, but they are only saved until the device is reset or turned off. You must Commit the changes to saves them permanently. Use the Commit & Reboot menu to commit changes to permanent storage. After you have submitted all the configuration changes you want to make for this session, click on the Commit & Reboot button in the Admin folder to view the Commit & Reboot page. Figure 29. Commit and Reboot To save current configuration settings as they have been submitted click in the Reboot Mode drop-down list; it does not affect the commit process.) . (Disregard the selection The changes are now saved to permanent storage (flash memory). Reboot the Router To reboot the device using the Configuration Manger, display the Commit & Reboot page, select the appropriate . reboot mode from the drop-down menu, and then click IMPORTANT Do not reboot the device using the Reset button on the back panel of the Router to activate new changes. This button resets the device settings to the manufacturer’s default values. Any custom settings will be lost. 46 DSL-500G ADSL Router User’s Guide Reboot Options Select the reboot option from the pull-down menu. The options are a described here: Reboot A simple reboot. This will put into effect any configuration changes that have been successfully committed to flash memory. Reboot From Last Configuration This will reboot the device using the current settings in permanent memory, including any changes you just committed. Reboot From Default Configuration This reboots the device to default settings provided by your ISP or the manufacturer. Choosing this option erases any custom settings. Image Upgrade Use the Image Upgrade menu to update firmware from a file on your system. Figure 30. Image (Firmware) Upgrade Upgrade File: Type in the full path and file name of the firmware file to be uploaded. Alternatively you may click the Browse button to search for the file on your system. When the filenames have been entered, click the Upload button to commence loading the firmware file. If the upload is successful, a message informs you that is was successfully loaded and asks you to reboot the device. Go to the Reboot menu and perform and simple reboot. If the firmware does not load, an error message informs you to try the upload again. Check the filenames and attempt to upload again. If the file still will not load, reboot the device and try again. 47 DSL-500G ADSL Router User’s Guide Diagnostics The diagnostics feature executes a series of test of your system software and hardware connections. Use this feature when working with your ISP to troubleshoot problems. Figure 31. Diagnostics Window Select the Virtual Circuit and click the Submit button. A message will appear informing you if the loop test succeeded or failed. The diagnostics utility will run a series of test to check whether the device's connections are up and working. This takes only a few seconds. The program reports whether the test passed or failed. A test may be skipped if the program determines that no suitable interface is configured on which to run the test. 48 DSL-500G ADSL Router User’s Guide Alarms The Configuration Manager can be used to view alarms that occur in the system. Alarms, also called traps, are caused by a variety of system events, including connection attempts, resets, and configuration changes. Although you will not typically need to view this information, it may be helpful in working with your ISP to troubleshoot problems you encounter with the device. (Despite their name, not all alarms indicate problems in the functioning of the system.) To display the Alarm page, log into the Configuration Manager, click the Alarm button in the Admin folder. Figure 32. Alarm/Trap Information Page Listed under Alarm/Trap Information are the time and date of each recorded alarm event, the type of alarm, and a brief statement indicating its cause. To remove all entries from the list, click the Clear button. New entries will begin accumulating and will display when you click the Refresh button. If you want to display an automatically updating Alarm table, you can click the Alarm Monitor button to display a separate Alarm Monitor window. Figure 33.

These devices are low pass filters and are variously referred to as in-line filters, micro-filters, line splitters or split line filters. They are easy to install and use standard telephone connectors and cable. For some ADSL clients, a telecommunications technician will be sent to the client’s premises to modify the telephone line, usually at the point where the telephone line enters the building. If a technician has divided or split your telephone line into two separate lines - one for regular telephone service and the other for ADSL – then you do not need to use any type of filter device. Follow the instructions given to you by your ADSL service provider, ISP or telephone company about where and how you should connect the Router to the ADSL line. In-Line Filters Two common styles of low pass filters are shown in this section, the first is an in-line filter and is illustrated in Figure 16 below. In-line filters are easy-to-install, in-line devices, which attach to the telephone cable between the telephone and wall jack. Figure 34. In-line Filter Installation Note: Do not install an in-line filter between the Router and the telephone jack. In-line filters are only intended for use with regular telephones, Fax machines and other regular telephone devices. 51 DSL-500G ADSL Router User’s Guide Split Line Filter If you are instructed to use a split line style filter you must install the device between the Router and the phone jack. Use standard telephone cable with standard RJ-11 connectors. The splitter has three RJ-11 ports used to connect to the wall jack, the Router and if desired, a telephone or telephone device. The connection ports are typically labeled as follows: Line - This port connects to the wall jack. ADSL – This port connects to the Router. Phone – This port connects to a telephone or other telephone device. The diagram below illustrates the proper use of the split line style filter. Figure 35.
